Mandatory information disclosure and innovation:Evidence from the disclosure of operational information

We use a quasi-natural experiment wherein the Shanghai Stock Exchange requires listed companies in certain industries to disclose operational information and a staggered difference-in-differences model to examine the impact of mandatory information disclosure on corporate innovation. We find that companies subject to mandatory operational information disclosure show significantly increased innovation. This effect is pronounced for companies classified as non-state-owned enterprises, facing severe financing constraints and a high degree of shareholder tunneling behavior and in competitive and high-tech industries. Although mandatory operational information disclosure reduces their competitive advantage, companies appear to compensate by increasing innovation. Our study highlights the positive impact of mandatory operational information disclosure, indicating that it contributes to the highquality development of both capital markets and companies.
